Bottled water costs about $1.50. Cases of water usually cost $5 and you only get 24-36 bottles. We use millions of gallons of oil each year producing disposable water bottles that usually end up in landfills.
Brita or Pur water filters are great options. You have to refill them, and wait for the water to filter through before you can pour a glass, but you can’t take the filter with you.
There’s a better solution: Water Bobble. It’s a $10 water bottle with a filter attached to the spout. It filters the water as you drink solving both the portability issue with water filters and the cost of bottled water.
They last for 300 fills (about 40 gallons of water). Filter replacements are only $5 and come in a variety of colors.
Check out the water bobble.
P.S. This makes a great Christmas Gift!
